The Laikipia Predator Project

It’s called the Laikipia Plateau. It sits along the equator in central Kenya, in the shadow of snow-capped Mount Kenya. Laikipia’s vast grasslands, riverbanks, and watering holes attract a rich array of wildlife, including some of Kenya’s largest numbers of rhinos, elephants, leopards, and buffalo. Researchers say the area — about 2 million acres — also supports nearly 200 African lions.

Laikipia is also home to people, including Maasai herders, who often come into conflict with lions that have learned to prey on easy-to-catch cows. The end result, too often, is dead cattle and dead lions.

In hopes of protecting both lions and farmers, local communities have embarked on a model experiment in wildlife-friendly land management called the Laikipia Predator Project, sponsored by the Wildlife Conservation Society and an array of other conservation groups. One of its main goals is to help local farmers protect their livestock from lions so they don’t have to kill them.

“Our studies have shown, not surprisingly, that properties that lose fewer livestock to predators tend to kill fewer predators,” write project leaders Laurence Frank and Rosie Woodroffe of the Mpala Research Centre in Kenya. “This suggests that we can conserve predators more successfully if we can prevent them from killing livestock. Better management may not only reduce livestock losses today — it should also prevent young predators from learning to take stock in the first place.”

The science of predator management is in its infancy, the pair says, “and every livestock producer has their own opinions on which practices best protect stock.” So one aim of the project has been to test which approaches work best. So far, the tests show that the best solutions employ basic common sense and are not very expensive, project leaders explain.

For instance, the studies have found that the design and construction of “bomas” — traditional corrals for sleeping livestock — are key to protecting livestock from lions. “The stronger the better,” project officials advise, adding that bomas built from thorny acacia bushes work better than those made from solid posts or stone. The researchers also discovered that the height of boma walls was much less important than their thickness. “Thick walls were especially effective at preventing lion attacks, presumably because they prevented cattle from breaking out,” the researchers concluded.

The studies have also revealed some other tricks. It helps to divide bomas into several “rooms,” for instance, and to place them near human residences. An armed guard nearby, along with a dog or two, also helps, although dogs can sometimes transmit diseases to wildlife. (In the Serengeti, domestic dogs were the source of a virus that killed many lions in the 1990s.)

The Laikipia researchers are now testing the idea that lions are less likely to attack livestock where there is plenty of wild prey nearby. In The Vanishing Lions, for instance, viewers follow scientists with the Wildlife Conservation Society as they track lions that are wearing radio collars. The collars are used to study the cats’ hunting patterns and to try to understand why some prides develop a taste for livestock while others do not.

Ultimately, project officials hope that the “predator-friendly management that we develop as a community in Laikipia will be a model for better conservation in the rest of Africa.” So far, the results are promising, as the Laikipia plateau continues to be one of the few places in Kenya where predator populations are growing, not dwindling.
Africa's lion population appears to be declining at an alarming rate. NATURE's THE VANISHING LIONS searches for explanations and solutions to the troubling trend. Across Africa, the King of Beasts is in trouble. In the late 20th century, wildlife preserves were created to curtail safari hunting, but the African lion population continues to decline. Their numbers have dwindled from 100,000 in the early 1990s to no more than 30,000 and as few as 16,000 today. What could be endangering the King of Beasts?

In the mid-1990s a mysterious disease spread rapidly through the lion population in Tanzania and Kenya. An investigation revealed that the big cats had contracted canine distemper from jackals and hyenas that were picking it up from dogs in nearby villages. The spread of the disease was quickly halted and today lion numbers in the affected areas are back to previous levels. If canine distemper was halted, why have lions continued to decline? An ever-expanding human population has led to competition between herders and lions for land and food. Lions living at the edge of the preserves sometimes stray from protected areas in search of easy prey. The Maasai and other ranchers will often kill them to protect their livestock and source of livelihood.

But as NATURE's THE VANISHING LIONS shows, Africans are now struggling to reverse the decline. Everyone from scientists and conservationists to Maasai herders and ranchers is working together to find solutions. Travel to Kenya's famed Serengeti Plains, the wildlife-rich Laikipia Plateau, and elsewhere in Africa as NATURE explores efforts to allow people and lions to coexist and prosper.
